According to “The Mirror,” the mist is produced by American company Vapshot’s machine, which vaporizes a £30 ($37) bottle of flavored Cîroc vodka and dispenses it into balloons.

While Vapshot claims the balloons are a safe and fun way to consume alcohol, public health officials are concerned the practice could lead to an increase in alcohol poisoning.

This isn’t the first time vaporized alcohol has popped up in England. In 2018, British brand Whitley Neill released three vaporized gins in London bars. Patrons sipped the fine mist through a straw out of mechanical orbs in variations including a London dry gin, raspberry gin, and rhubarb and ginger.
